"Let it suffice to say that I would NEVER recommend this company to anyone. They take advantage of people who are in a crisis situation with family members, do not make clear the contract and have a ridiculous return policy. I recommend you research for companysies who do the same thing and choose another one. I fully intend to email every rehab hospital I can and recommend they NOT suggest Oxygentogo. Charged us $160 more than we expected. And did so without emailing us to let us no that the charge was incurred."
